Description

  The present invention relates to a slit-forming form structure and a reinforcing metal fitting that have a configuration capable of incorporating a structural slit material reinforcing component with high versatility and can improve the performance of reinforcing the structural slit material.

  In general, in a concrete structure such as a reinforced concrete structure, a structural slit material is provided vertically in the vertical direction at the boundary between a column and a wall so that seismic performance can be improved. The structural slit material is provided in the concrete placement space between the mold plates assembled with the separator, and is embedded in the placement concrete. The structural slit material may be deformed or displaced from the mounting position by the side pressure of the cast concrete. For this reason, the structural slit material is supported and reinforced.

  For example, in “Reinforcement structure and reinforcement member for earthquake-resistant slit material” in Patent Document 1, a support member for an earthquake-resistant slit material having a reinforcing member fitting groove formed on a side surface portion, and a retaining rod that is rotatable on a locking member. The reinforcing structure of the seismic slit material is constituted by a reinforcing member that is supported and has a reinforcing plate having an outer peripheral shape having a short diameter and a long diameter fixed to the tip of the holding rod. By rotating the holding rod by a predetermined angle, the peripheral portion of the reinforcing plate is fitted into the reinforcing member fitting groove of the supporting member, and the core member is reinforced from the side by the reinforcing member.

  Two supporting members each having a fitting groove are attached to both ends in the width direction of the earthquake-resistant slit material. The reinforcing plate of the reinforcing member is fitted into the fitting groove portion of each supporting material so as to pass to these two supporting materials. Further, the holding rod fixed to the reinforcing plate is disposed between the center of the separator supported at both ends by a pair of molds and the center in the width direction of the earthquake-resistant slit material.

  As shown in FIG. 1, the formwork structure used when constructing a concrete structure is well known in the art. By assembling a pair of formwork plates 2R, 2L with a separator 1 for adjusting the distance, Formwork plates 2R and 2L are arranged facing each other. A concrete placement space 3 is formed between the pair of mold plates 2R and 2L supported by the separator 1. The separator 1 that connects the pair of mold plates 2R and 2L is supported at both ends 1R and 1L in the longitudinal direction by the mold plates 2R and 2L. This embodiment demonstrates the case where a concrete wall is located in a boundary with a pillar and a slit is provided vertically in the vertical direction.

  When the slit is formed, the mold structure includes joint materials 4R and 4L attached to the pair of mold plates 2R and 2L, and a structural slit material 5 provided at an attachment position of the joint materials 4R and 4L. A pair of support members 6R, 6L that attach the structural slit material 5 to the pair of joint materials 4R, 4L and support them on the mold plates 2R, 2L are used.

  The structural slit material 5 is formed of a conventionally known material, is formed in a long strip shape having a thickness according to the vertical height of the wall, and is provided upright in the concrete placement space 3. The structural slit material 5 is installed such that both side edges 5R, 5L in the width direction face a pair of mold plates 2R, 2L located on the sides thereof, and the front and back surfaces 5a face the concrete placement space 3. Is done.

  As shown in FIGS. 1 and 2, a pair of support members 6 </ b> R and 6 </ b> L is used so as to correspond to the respective side edges 5 </ b> R and 5 </ b> L in the width direction of the structural slit material 5. The support members 6R and 6L are made of synthetic resin, and are formed to be long according to the vertical height of the structural slit material 5.

  The support members 6R and 6L include a first grip portion 6b having a U-shaped cross section that forms a first fitting recess 6a that fits in the width direction side edges 5R and 5L of the structural slit material 5, and joint materials 4R and 4L. And a second grip portion 6d having a U-shaped cross section that forms a second fitting recess 6c into which is fitted. The width direction side edges 5R and 5L of the structural slit material 5 are fitted to the first fitting recesses 6a of the two support members 6R and 6L, respectively. The structural slit material 5 is fitted to the support members 6R and 6L from the width direction. It is caught.

  The joint materials 4R and 4L are fitted into the second fitting recesses 6c of the two support members 6R and 6L, respectively. In the illustrated example, a wooden joint material 4L formed so as to be elongated in accordance with the height in the vertical direction of the wall, so-called joint rod, is fitted into the second fitting recess 6c of one support member 6L. ing. The second fitting recess 6c of the other support member 6R is filled with a caulking agent as a joint material 4R. A joint material 4L made of joint rod is attached and fixed to one mold plate 2L with a nail 7 or the like. The joint material 4R made of a caulking agent is attached in close contact with the other mold plate 2R. The joint material 4R may be a joint stick similarly to the joint material 4L instead of the caulking agent.

  Therefore, the mold structure in the case of forming the slit is that a pair of joint materials 4R and 4L are attached to the mold plates 2R and 2L so as to face each other, and the width direction side between the mold plates 2R and 2L. The structural slit material 5 is arranged so that the edges 5R and 5L face the joint materials 4R and 4L, respectively, and a pair of supports for mounting and supporting the structural slit material 5 on the pair of formwork plates 2R and 2L The members 6R and 6L are mounted on the side edges 5R and 5L in the width direction of the structural slit material 5 and assembled to the joint materials 4R and 4L.

  When reinforcing the structural slit material 5 to prevent it from being deformed or displaced, as shown in FIGS. 1 to 4, the support members 6R and 6L attached to the structural slit material 5 and the separator are used. Reinforcing hardware 8R and 8L are provided between the two. In order to attach the reinforcement hardware 8R, 8L to the structural slit material 5 side, the first grip portion 6b of the support members 6R, 6L faces the concrete placing space 3, in other words, faces the separator 1 side. A pair of claw bodies 6e and 6e are provided over the entire length in the vertical height direction of the support members 6R and 6L. In the illustrated example, a pair of claws 6e and 6e are provided on the front and back of the first grip portion 6b so that the support members 6R and 6L can be used on both sides.

  The claw bodies 6e and 6e are formed so as to protrude from the first grip portion 6b, whereby receiving grooves 6g and 6g having groove bottoms 6f and 6f are formed in the back of the claw bodies 6e and 6e. Therefore, a pair of receiving grooves 6g and 6g are formed by the pair of claws 6e and 6e, and the pair of claws 6e and 6e are horizontally separated with a gap C so that the pair of receiving grooves 6g and 6g face each other. Are provided facing each other.

  Since the supporting members 6R and 6L are individually attached to the side edges 5R and 5L in the width direction of the structural slit material 5 adjacent to the mold plates 2R and 2L, the reinforcing hardware 8R and 8L are respectively attached to the supporting members 6R. , 6L and a pair of separators 1R and 1L in the longitudinal direction of the separator 1 which are close to the mold plates 2R and 2L and are supported by the mold plates 2R and 2L. The pair of reinforcement hardware 8R and 8L is placed in the concrete placement space 3 and acts on the front surface 5a or the back surface 5a of the structural slit member 5, and the concrete side pressure applied from the support members 6R and 6L is applied to the separator 1. Transmit and support. In the illustrated example, the reinforcing hardware 8R, 8L is disposed on one side of the structural slit material 5, but may be provided on both sides of the structural slit material 5.

  FIG. 3 shows reinforcing hardware 8R and 8L. 3A is a side view of the reinforcing hardware 8R, 8L, FIG. 3B is a front view, and FIG. 3C is a plan view. The reinforcement hardware 8R, 8L is made of metal such as steel, and one end is coupled to the pressure receiving plate portion 8a held by the pair of claws 6e of the support members 6R, 6L, and the pressure receiving plate portion 8a. The other end is engaged with the separator 1 and includes support members 6R and 6L that hold the pressure receiving plate portion 8a and connecting members 8b that connect the lengthwise ends 1R and 1L of the separator 1.

  As long as the connection member 8b can connect between the pressure receiving plate part 8a and the separator 1, a form will not be ask | required. In the illustrated example, a rod-shaped connecting member 8b is shown. One end of the rod-shaped connecting member 8b is screwed to the pressure receiving plate portion 8a. Further, a locking member 9 is provided at the other end of the connecting member 8 b, and the locking member 9 is locked to the separator 1.

  In the illustrated example, the locking member 9 is screwed into the thread of the connecting member 8b and is provided so that its position can be adjusted in the length direction of the connecting member 8b. The locking member 9 is U-shaped that exhibits springiness, has a gripping portion 9b on the side of the distal end 9a that can be expanded and contracted by springiness, and when the separator 1 is pushed in between the distal ends 9a that are expanded by springiness. Then, it is restored, and is held in such a manner that it is clamped to the separator 1 by the grip portion 9b. By locking the separator 1, the support member 6 </ b> R, 6 </ b> L that holds the separator 1 and the pressure receiving plate portion 8 a is connected by the connecting member 8 b.

  As shown in FIG. 5, the pressure receiving plate portion 8a is formed in a quadrilateral shape having four diagonal portions. In the example of illustration, the pressure receiving plate part 8a of the unequal side square shape from which the length of each side differs is shown. Of the four sides of the pressure-receiving plate portion 8a, at least one side Sa along the vertical direction of the claw body 6e is set so as to incline so as to form an acute angle θ with respect to the claw body 6e. The In the illustrated example, the other side opposite to the one side Sa is set in a positional relationship substantially parallel to the claw body 6e.

  The outer dimensions of the pressure receiving plate portion 8a are set so that the side Sa, which is inclined with respect to the claw body 6e, is inserted along the claw body 6e from the gap C. Further, in the four-sided pressure receiving plate portion 8a of the illustrated example, in one side Sa inclined with respect to the claw body 6e, the diagonal portion where the pressure receiving plate portion 8a is narrowest and the diagonal portion Da where the width is widest. The dimension between the diagonal part Da that becomes wide and the diagonal part Db that faces this diagonally is between the diagonal part that becomes narrow and the diagonal part that faces this diagonally. Longer than the dimension. And the dimension between the wide diagonal part Da and the diagonal part Db which faces this is set longer than the clearance gap C between the said nail | claw bodies 6e in the direction where a pair of nail | claw body 6e faces. In other words, the dimension Y between the claw bodies 6e of the diagonal portions Da and Db is set longer than the gap C.

  The state shown in FIG. 5A is obtained by arranging any one side Sa to be inclined with respect to the nail body 6e and setting the dimension between any diagonal parts Da and Db in the diagonal direction as described above. By rotating the pressure receiving plate portion 8a from the state shown in FIG. 5B, each of the diagonal portions Da and Db can enter the receiving grooves 6g. As shown in FIG. 4, the pressure receiving plate portion 8a can be held by the pair of claws 6e.

  That is, in the quadrilateral shape that fits in the gap C between the nail bodies 6e in a state in which the one side Sa inclined with respect to the nail body 6e is aligned with the nail body 6e, any one side Sa and the nail body 6e have an angle. On the diagonal line where the dimension is longer than the length of each side of the quadrilateral shape with respect to the side Sa forming the angle θ with the nail body 6e, with the diagonal part Da at the wide position as the starting point. The distance between the pair of diagonal parts Da, Db is set to be longer than the gap C between the nail bodies 6e, and by rotating the quadrilateral shape between the nail bodies 6e, the pair of diagonal parts Da, Db is configured to enter the receiving groove 6g and be held by the claw body 6e. The pressure receiving plate portion 8a is integrally provided with a knob portion 8c for rotating operation, which is bent from the pressure receiving plate portion 8a.

  FIG. 6 shows another example of the form of the pressure receiving plate portion 8a. In this example, the outer shape of the pressure receiving plate portion 8a is along the vertical direction of the claw body 6e, and the two sides Sa sandwiching the connecting member 8b are both inclined with respect to the claw body 6e. By rotating the pressure receiving plate portion 8a inserted between the claw bodies 6e from the gap C between the claw bodies 6e, a pair of diagonal portions Da and Db located on the longer diagonal line enter the receiving groove 6g. . In any of the pressure receiving plate portion 8a shown in FIG. 3 and FIG. 6, the substantially triangular diagonal portions Da and Db of the pressure receiving plate portion 8a can be made to enter the receiving groove 6g. Since the diagonal portions Da and Db are wide, the pressure receiving plate portion 8a can be efficiently held on the claw body 6e.

  The diagonal portions Da and Db that have entered the receiving groove 6g are restricted by the groove bottom 6f against rotation more than necessary. In other words, the diagonal portions Da and Db only need to enter the receiving groove 6g. Therefore, unless the rotation is excessive, the rotation is not restricted by the groove bottom 6f. When the diagonal portions Da, Db are excessively rotated, for example, when the diagonal portions Da, Db are rotated to a position where they are horizontally aligned, there is almost no span X for holding the pressure receiving plate portion 8a in the vertical direction of the claw body 6e. Although the holding strength is weakened, the excessive rotation can be restricted by the groove bottom 6f, so that the distance between the diagonal portions Da and Db held by the claw body 6e can be increased, and the pressure receiving plate portion 8a can be The claw body 6e can be strongly held with a long span X in the vertical direction. Thereby, the bending and rotation of the structural slit material 5 can also be suppressed effectively.

  On the quadrilateral pressure receiving plate portion 8a, convex portions 10 are formed at diagonal portions Da and Db that enter the receiving groove 6g. In the pressure receiving plate portion 8a in the form of FIG. 3 and FIG. 5, one convex portion 10 is formed in a wide diagonal portion Da with respect to one side Sa inclined with respect to the claw body 6e, and the other convex portion. The part 10 is formed in the diagonal part Db that is diagonally opposite to the one diagonal part Da.

  In the illustrated example, a protruding portion is formed on the diagonal portion Db on the other side, and a convex portion 10 is formed on this protruding portion of the diagonal portion Db. The convex portion 10 may be formed on the pressure receiving plate portion 8a on the surface on the side of the connecting member 8b or on the surface opposite to the connecting member 8b. The convex portion 10 may be formed by any method, such as press molding, cutting and raising, and forming a projection by pouring molten metal, as long as it protrudes from the pressure receiving plate portion 8a.

  Next, the operation of the slit forming form structure and its reinforcing hardware according to this embodiment will be described. When the structural slit member 5 is installed and reinforced with the reinforcing hardware 8R, 8L, first, the joint material 4L is fixed to one mold plate 2L with a nail 7 or the like, and one support member 6L is attached to the joint material 4L. Is attached, and one side edge 5L in the width direction of the structural slit material 5 is attached to the one support member 6L. The other support member 6R filled with the joint material 4R is attached to the other side edge 5R in the width direction of the structural slit material 5. In parallel with or in parallel with this operation, one end 1L in the length direction of the separator 1 is attached and fixed to one mold plate 2L.

  Next, the pressure receiving plate portions 8a of the reinforcing hardware 8R and 8L are attached to the claws 6e of the pair of support members 6R and 6L. The reinforcing hardware 8R and 8L can be attached to any position in the vertical direction of the claw body 6e in accordance with the height position of the separator 1. When attaching the reinforcing hardware 8R, 8L, the pressure receiving plate portion 8a is inserted into the gap C between the claws 6e, the knob 8c is rotated, and the convex portion 10 of the pressure receiving plate portion 8a is received in the receiving groove 6g. The pressure receiving plate portion 8a is fixed to the support members 6R and 6L. Thereafter, one end of the connecting member 8b is screwed to the pressure receiving plate portion 8a. Further, the position of the locking member 9 at the other end of the connecting member 8b is adjusted, and the locking member 9 is locked to the longitudinal end portions 1R and 1L of the separator 1.

  Thus, a pair of reinforcing hardware 8R and 8L connected to the longitudinal ends 1R and 1L of the separator 1 are attached to the structural slit member 5 on both side edges 5R and 5L in the width direction. After that, the other mold plate 2R is installed, the other end 1R in the length direction of the separator 1 is attached and fixed to the mold plate 2R, and the mold plate 2R is in close contact with the joint material 4R.

  When the slit forming mold is assembled in this way, concrete is placed in the concrete placing space 3 between the pair of mold plates 2R and 2L. When concrete is placed in the concrete placement space 3, the concrete side pressure acts on the surface 5a of the structural slit material 5 on the side opposite to the side on which the reinforcement hardware 8R, 8L is installed. The reinforcing metal parts 8R and 8L receive the concrete side pressure acting on the structural slit material 5 through the support members 6R and 6L, and the received side pressure is transmitted to the separator 1 by the connecting member 8b and supported.

Since it can be connected in the vicinity of the mounting support position, the separator 1 is not easily deformed. Therefore, deformation and displacement of the structural slit material 5 can be prevented appropriately, and the performance of reinforcing the structural slit material 5 is ensured. It can improve and can install a slit exactly.

  Unlike the background art, the width dimension of the structural slit material 5 is wide and narrow, because the reinforcing hardware 8R, 8L is individually provided for each of the pair of support members 6R, 6L provided on both side edges 5R, 5L in the width direction of the structural slit material 5. That is, without depending on the wall thickness, the supporting members 6R and 6L and the reinforcing hardware 8R and 8L, which are the reinforcing parts of the structural slit member 5, can be incorporated with high versatility as common parts.

  Further, the attachment of the reinforcing hardware 8R, 8L to the support members 6R, 6L (claw body 6e) can be completed by an operation of twisting and turning the pressure receiving plate portion 8a. Even when the bars are arranged, the work can be completed easily in a narrow space.

  Since the locking member 9 locked to the separator 1 is provided on the connecting member 8b, and the locking member 9 is provided on the connecting member 8b so that the position of the locking member 9 can be adjusted, the structural slit material 5 and the separator 1 are arranged according to the construction position.
